request-promise implementation returning `null`

Question

Any ideas why the value returned from getBatchedContent is null , given the code sample below?

import rp from 'request-promise';
import _ from 'lodash';

function getBatchedContent(size, page) {
  return Promise.resolve(fetchBatchedContent(size, page)); // Getting `null` here.
}

function fetchBatchedContent(size, page) {
  var options = {
    uri: `http://www.example.com/posts?type=vogue-fashion-shows&filter[posts_per_page]=${size}&page=${page}`
  };

  return rp(options)
    .then(function (res) {
      res = JSON.parse(res);
      // res is an array of content objects.
      return _.map(res, function (obj) { // logged value of `_.map()` is correct.
        return transformContent(obj);
      });
    });
}

function transformContent(obj) {
  return {
    id: obj.ID,
    title: obj.title,
    // etc.
  };
}

Perhaps add a .catch(function (error) {debugger;}) to fetchBatchedContent . Does it return what you expect?

I'm not sure what you're inputting into Promise.resolve that can directly result in null ? That seems very odd to me, even Promise.resolve(Promise.reject('foo')) would return a Promise. (a rejected one).
